Zusammenfassung:PROBLEM TO BE SOLVED: To easily regulate a printing density inexpensively by incorporating a plurality of dividing portions having different thicknesses in a conveying belt for conveying a sheet disposed through a printing unit, and changing a pressing pressure to the sheet due to a difference of the portions disposed at the unit. SOLUTION: A pressing roller 10 as a pressing means provided separably at an outer periphery 3a of a plate cylinder 3 is passed through an opposed printing unit 11, and conveyed toward a delivery unit 12. A sheet 19 conveyed via an electrostatic attraction belt 14 is sandwiched between the roller 10 and the cylinder 3 in the unit 11. An ink is immersed from pores of an engraved master from an interior of the cylinder 3, transferred to the sheet 19 to print an image. This printed sheet 19 is conveyed toward the unit 12 while the sheet 19 remains electrostatically attracted to the belt 14, then released from the attraction by a destaticizing separating means 15, separated from the belt 14. Dividing portions 140, 141, 142 having different thicknesses are continuously provided at the belt 14.
